Spectroscopic Insights into Metal Complexes: Toroidal Properties, Magnetism, and Solvatochromism

Compounds exhibiting quantum magnetic properties are of current interest for their potential use in quantum computing or spintronics. These magnetic properties, and the relaxation of magnetic excitations, are not fully understood and need further exploration for more widespread use in quantum information science applications. To further understand the magnetic relaxation and magnetic structure of these materials we have sought to study them using advanced methods such as magneto couple spectroscopy or neutron scattering experiments. The primary focus of this dissertation is the study of the magnetic structure, relaxation, and synthesis of molecular magnetic compounds such as single-molecule magnets, single-molecule toroids, and spin-1 Haldane topological spin chains. These are studied using a combination of routine and advanced techniques, such as inelastic neutron scattering, far-IR magneto spectroscopy, high-field and -frequency electron spin resonance, or polarized neutron diffraction to directly observe magnetic transitions or magnetic structure.
